SH UTTER-FASTENER.

SPECIPICATIQN forming part of Letters Patent No. 374,981, dated December20, 1887.

Application filed July 19, 1887. Serial No. 244,757. (No model.)

To aZZ whom it may concern:

Be it known that I, FRANK B. humour, a citizen of the United States,residing at Fleur ington, in the county of Hunterdon and State of NewJersey, haveinvented certain new and useful Improvements in Shutter-Fastening Bars, Bolts, and Operating Mechanisms; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will. enable others skilled in the art to which itappertains to make and use the same.

My invention relatesto an improved shutter-bar-fasteuing bolt or rod,and to mechanism whereby the shutter'fastening bolt and the bar aremoved in and out of locking and fastening position from the inside of aroom without opening the window and without manipulation from theoutside of the building.

In the accompanying drawings, Figure 1 is a View of a pair of shutterswith a windowframe and a portion of the surrounding wall provided withthe fastening shutter-bar and Fig. 2 is a horizontal section through thefulcrum portion of the bar and the adjacent parts of the building. Fig.8 is a View ofra modified construction of the fulcrum-shaft; and Fig. 4is the shuttenbar fastener,shown in two different positions, one in fulllines and the other in dotted lines.

The letter A in the drawings represents an ordinary window-frame, a asashes, B B shutters, and O a shutterfastening bar.

The shutter-fastening bar Gis firmly attached to the square head d of afulcrumshaft, D, which is fitted in the vertical portion a of thewindow-frame and extends into the room of the house, where it isprovided with a crank or a more elegant operating deviceas, forinstance, a hand-wheel, ri-which latter serves as the means for swingingthe bar 0 across the shutters, as shown by full lines, or away from andout of range of the shutters, as shown in dotted lines in Fig. 1.

The end of the bar C while in a horizontal position, is supported andheld fast by a stepped hook, d, formed at the end of a sliding lock boltor rod, D. The step d of the hook at is provided with an upperoutwardlyinclined projection, d, whereby the end portion of the bar 0 isguided in its descent into the hook (P. The fastening bolt or rod D isfitted into the vertical portion a of the windowframe, and is at theinner side of said frame provided with a cylindrical end portion, 62having an annular groove, (2. To the end portion at a handle, E, isfitted,which has an inclined face, 6, and set-screw e, the latterextending into the groove d,so that the handle can be turned around theportion d without sliding 0E longitudinally. Between the handle E andwindow-frame a hollow boss, 6 having a flange, c and an inclined face,0", is placed. Through the boss (2 the fastening bolt or rod D passes,and thus the inclined faces 6 and 0* stand opposite each other and causethe said bolt 0r rod to be drawn against the bar 0 when the handle E isturned down. as in Fig. 4, and when the handle E is turned up, asindicated by dotted lines in the same figure, the fastening belt or rodD becomes released and may be pushed out by hand or by a suitabletension-spring, thereby moving the hook d sufficiently away from the bar0 to permit its swinging up to the position shown by dotted lines inFig. 1,in order to fasten the shutters.

For the purpose of facilitating the operation of raising the bar 0 abalance-weight, F*, is, by means of a cord or chain, f, attached at asuitable place, f, to the bar, the cord f being suspended on a pul1ey,ffixed to the windowframe,and the weight F moving in a guiding andprotecting tube, f suitably fastened to the wall or window-frame.

When the window-shutters are to be opened, the handle E is turned up andthe bolt or rod D pushed outwardly. The hand-wheel d is then turned andthe bar 0 turned up in the position indicated by the dotted lines, andthe shutters can now be swung open by means of inside operated shutterworkers, as at a", which may be of any well-known construction. When thewindowshutters are to be locked, they are first closed together, thenbymeans of the hand-wheel d the bar 0 is turned down into the hook d,whereupon the handle E is turned down, the hook d" drawn against andpartly over the bar 0,.and thereby said bar 0 is securely locked acrossthe shutters. This described operation is performed entirely from theinside of the building and without opening windows or shutters.

Instead of the vertically-gravitating weight 13* and pulley f forbalancing the bar 0, a weight, F, may be used upon a rear extension, 0,of the bar 0, or a spring, 0, coiled around the shaft D and fastened tothe bar G and windowframe in a suitable manner, may be success fullyemployed, and other means than the cam may be adopted for moving thelocking bolt or rod D out of hooking position with the bar 0.

The fulcrum-shaft D might be provided with an ordinary ratchet and pawl,as (1 61 or other suitable device for holding it from being turned afterthe bar 0 has been adjusted upon the bolt or rod D, and in such case itwould not be necessary to have the hook d overhang the bar. I, however,prefer to have the hook d" overhang the bar, as shown.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The combination of the shutter-fastening bar 0, pivoted to afulcrum-shaft, D, which is extended into the room of a building on whichthe shutters are hung, and is provided with an operating handle or wheelon its inner end, amechanical device for holding the bar 0 in itsfastening position, and the bolt or rod D, upon which the bar rests andis confined, substantially as and for the purpose described.

2. A shutter-fastening mechanism operated from the inside of a building,consisting of a swinging bar, 0, operating-shaft D, and slid ingfastening bolt or rod D, provided'with a hook, (2 substantially as andfor the purpose described.

a window-frame, of the balanced swinging fastening-bar O and the slidinglock bolt or rod D, having hook 01, both operated in the interior of abuilding, substantially as and for the purpose described.

In testimony whereof I aifix my signature in presence of two witnesses.
